Sexual reproduction
How many organism are involved in sexual reproduction
Two organisms
What is asexual reproduction
When one organism produces offspring
What is natural selection?
Animal with the most desirable traits, survives and reproduces
What is selective breeding?
When humans breed animals for the best traits
What is sexual reproduction
When two organisms produce offspring
What is it called when the parent cell divides into two
Binary fission
What animal was Charles’s Darwin’s theory on
finches in the Galapagos islands
Why is selective breeding used?
To improve life
Why does sexual reproduction make it easier to adapt in environment
The most desirable traits are passed on
How does asexual reproduction save energy
You don’t need to waste energy on finding a mate
Who discovered the theory of natural selection?
Charles Darwin
What does selective breeding benefit
It benefits the amount of muscle and fat on a animal
what cells are involved in sexual reproduction
The female egg and the male sperm
What is fragmentation
When the organism gets separated into fragments and those fragments turn into new organisms
Why is natural selection more adaptable to changing environments?
The animals with undesirable traits die, and the animals with the best traits reproduce.
What is the main type of reproduction used in selective breeding
Sexual reproduction
what is genetic variation
When the off spring gain traits from both parents
Why can’t sexual produce produce diverse offspring
Offspring are genetically identical to each other and to their parent
His does mutation effect natural selection
It can add new and more desirable genetic variations
Why dose selective breeding occur?
It occurs to improve the animal
